GEO. COOK, OF NEW" HAVEN, CONNECTICUT.

LOCK FOR CARRIAGE-CURTAINS.

Specification of Letters Patent No. 8,626, dated January 6, 1852.

To all whom t may concern:

Be it known that I, GEORGE COOK, of New Haven, in the county of New I-Iaven and State of Connecticut, have invented a newl the annexed drawings, making part of this specification.

Figure l, Vis a side view of theknob, and Fig. 2, is a vertical view of the knob. Figr, is a vertical view of the eyelet. Fig. t, is a side view of the knob.

This invention consists p-rincipally in the construction and employment of a knob or button of peculiar form, in combination with an eyelet of peculiar form to match; so that by means of the two, coach curtains, carpets, knapsacks, or other articles constructed of leather or fibrous or other materials may be` more readily and effectually fastened than by o rdinary methods.

, The head A of the knob may be of a semiglobular, conical or other convenient form with a Vcircumferent` groove B, B, between the head and the base C, C, to receive the eyelet which constitutes a part of the lock. The periphery of the head has the form of a polygon, with siX, eight or any other convenient number of angles, and the `spaces between the angles, may be `either plain 4or concave. From the center of the base projects a screw shank D, which may be fur nished with a nut when occasion requires.

The eyelet F, F, is made in the ordinary form of metallic eyelets, with the exception that the central aperture G is made of the exact form of the periphery of the head, so that the latter will pass freely through the former, but that by a slight cha-nge in the relative position of either, the head is effectually detained. When this knob and eyelet are attached to the articles or parts which are to be thereby connected, they are so adjusted, relatively, that the eyelet must be slightly writhed or turned from its proper position in order to admit the knobhead to pass through it, whether for the purpose of connecting or disconnecting the pair. This fastening is adaptable to the securing of carpets and matting to floors, in which case the knob head may be made flat, and the shanks thereof may be inserted into the floor.

I-Iaving thus described the nature of my invention, of an improved lock, or fastening for coach-curtains, what I claim as my invention and desire to secure by Letters Patent, is,

l. The constructing or manufacturing of coach curtain locks, each consisting of a polygonal knob, and an eyelet having a polygonal central aperture of corresponding form and size, so that at certain relative positions, the knob head will pass freely through the eyelet, while in other relative positions the knob can not pass through the eyelets on account of the prominence. of its angles.

2. I also claim attachingthe knobs and eyelets to the articles which are to be thereby connected, in such relative positions that the knob head can not be made to pass through the eyelets, either for the purpose of connecting or disconnecting, unless the eyelet or knob is turned from its ordinary and proper position; both the knob and eyelet being constructed in the manner and for the purpose herein described.

In testimony whereof I have hereunto signed my name before two subscribing witnesses.

GEORGE COOK. Witnesses A. C. VATKINS, T. S. SMITH.
